Unauthenticated Updates

[myolbug]

I have Mint 9 64Bit and I went to update it, but it is showing 9 unauthenticated updates.
Here is the list and should I install any of them? I mostly use Mint for internet anti-piracy, so it is almost all internet.

Why would unauth updates even be released in the update stream?

Those look like packages you'd be getting from the main repos, so should be authenticated. You could try switching to a different update server, the one you're connecting to might be having problems.
